The purpose of this document is to provide information regarding the methodology and technology to be used
to measure atmospheric pressure. The goal is to ensure that data collected is accurate and consistent from
station to station as well as conforming to World Meteorological Organization (WMO) standards as much as
possible.
The nature and location of Alberta Environment and Parks (AEP) weather stations means that strict adherence
to WMO standards is not always possible. In these cases, discrepancies should be noted and technicians will
have to make decisions on how to best accommodate any issues.
No official formal standard operating procedure (SOP) for the measurement of atmospheric pressure has been
written by the Government of Alberta. Most knowledge has been passed on through demonstration,
collaboration, and mentorship. Guidance was gained from the WMO publication: Guide to Meteorological
Instruments and Methods of Observation (2008 edition, updated 2010).
